Tyler’s story: How a genetic test for stomach cancer changed this father’s life

As a loving husband and dedicated father, Tyler knew he had to make a drastic change in his life when his mother and older sister passed away from stomach cancer. Looking for answers, Tyler and his other sister Shelley, opted to take part in genetic testing. The results of this test would help them better understand their risk of a hereditary stomach cancer that is often diagnosed in its late stages – when treatment is no longer an option.

Cutting-edge research

With funding from the Canadian Cancer Society, Dr David Huntsman, a leader in the field of genetic markers for cancer, was able to conduct research on hereditary gastric cancers. By studying the DNA of families with the disease, he was able to find genetic changes that increased a family member’s likelihood of developing stomach cancer. This research would eventually assist people like Tyler and Shelley in making informed decisions about their cancer risk and treatments.

Family first

After using the genetic test that Dr Huntsman developed, it was revealed that Tyler and his sister carried the same genetic mutation that their mom and older sister had.

Knowing the risks and the impact of this disease in his family, Tyler decided to take charge of his health and chose to have his stomach removed. This procedure reduced Tyler’s chances of passing away from the disease from 70% to less than 1%.

“Deciding on the surgery was a no-brainer,” explains Tyler.

For Tyler, having his stomach removed meant that he would be able to see his sons grow up.

Empowering others through cancer research

Groundbreaking cancer research like Dr Huntsman’s is helping keep families like Tyler’s together. Today, Tyler is a devoted volunteer committee member, organizer and participant for the Canadian Cancer Society Relay For Life and continues to raise funds for cancer research so others can benefit from it like he did.

“Cancer is still taking many people’s lives, but you see so many people who are cancer survivors, all because of research,” says Tyler.

The Canadian Cancer Society invests in the best research across more than 100 types of cancers. As the largest national charitable funder of cancer research, we are committed to learning more about what causes cancer, how it develops, how best to treat it and how we can improve the quality of life for people living with cancer. With your support, we can continue investing in research that changes the lives of Canadians, like Tyler.

Tyler's story - how a gift in your will can help rewrite the future for families like Tyler's

[A polaroid-style photo appears of Tyler’s mother smiling on a boat.]

Tyler: I was 9 years old when my mother was diagnosed with stomach cancer.

[Tyler is speaking to the camera.]

Tyler: Life was perfect.

[Photos appear of Tyler’s family when they were younger. They are all happy and smiling. The photos include one of a young child on a Sea-Doo and one of Tyler’s mom smiling and holding one of her children.]

Tyler: My parents had a successful business, we had a nice home, we had a camp we would go to and a boat. It was a perfect life, and all that came crumbling down.

[A photo appears of Tyler’s sister, Jennifer, smiling.]

Words on screen: 17 years after losing his mother to stomach cancer, Tyler’s oldest sister Jennifer is diagnosed with the same disease.

[Tyler is speaking to the camera.]

Tyler: My reaction to my sister Jennifer being diagnosed with stomach cancer… My first thought was, “it's happening again?” And I couldn't understand why it would happen to our family twice. Unfortunately, it brought everything back, and I knew what was going to happen.

[A photo appears of Tyler dancing with Jennifer.]

Tyler: It was just as hard as an adult as it was as a child.

[Tyler, his wife, and their 2 sons are looking out over a lake.]

Tyler: Doctors suggested there could be a genetic link. We didn't find out until after Jennifer passed that we did test positive.

[A photo appears of Dr David Huntsman looking into a microscope.]

Words on screen: Canadian Cancer Society-funded research by Dr Huntsman leads to a breakthrough in genetic testing for hereditary stomach cancer.

[A photo appears of Dr David Huntsman smiling in a lab.]

Words on screen: Early detection and prevention of the disease is transformed, allowing those who test positive for a specific genetic mutation to have their stomach removed.

[Tyler is speaking to the camera.]

Tyler: The risk of getting cancer with this genetic mutation … It varies on the studies, but it's upwards of a 70% chance of developing it in your life.

[Tyler and his family are sitting on a park bench.]

Tyler: When I tested positive for the genetic mutation, I had already had my mind made up that I would have the surgery.

Words on screen: In 2010, Tyler opted to have this stomach removed.

[Tyler and his family are sitting on a park bench and feeding ducks.]

Tyler: One of the easiest factors for doing it was my other sister, Shelly, had gone through it first. It was easier to see the road that I would be going down.

[Tyler is speaking to the camera.]

Tyler: Knowing I had someone there with me the whole time helped.

[Tyler and his family, including his wife, Nikki, are petting animals at a farm.]

Tyler: The biggest supporter was my wife, Nikki. She helped and she really educated herself too, with the meals and eating and all that stuff that goes along with it.

[Tyler is feeding a baby goat at a farm.]

Tyler: Before the surgery, they found no traces of cancer.

[A bird lands on Tyler’s hand and starts eating from it.]

Tyler: And at the time of the surgery, they found no trace of cancer. But further biopsies found 5 tumours.

[Tyler is speaking to the camera.]

Tyler: So that just reaffirmed how important it was to go with the surgery.

[Tyler and his son are sitting on a bench overlooking a lake.]

Tyler: Having the surgery allowed me to have children of my own and continue with a life, and a great life.

[Tyler and his sons are playing video games.]

[A framed family photo in Tyler’s home appears.]

[Tyler is kayaking on a lake.]

Tyler: I feel 100% that I rewrote my future.

[Tyler is speaking to the camera.]

Tyler: Had I not gone with the surgery, I wouldn't be around to enjoy these moments.

[Tyler is feeding a baby goat at a farm while one of his sons sits beside him.]

Tyler: Research funded by the Canadian Cancer Society saved mine and my sister's life.

Help us create a future without cancer

February 4 is World Cancer Day, a global movement that brings people, organizations and governments together to raise awareness, honour those affected by cancer and drive collective action that can save and improve lives.

Every person’s unique cancer experience matters. By highlighting these diverse stories, we can drive more inclusive, people-centred care and meaningful change across out healthcare system.

We know that nothing big gets solved by one person or one organization. This World Cancer Day, join us to create a future without cancer.
